Atlus has posted a trailer showing off the first gameplay footage from Catherine, its provocative action-adventure title coming to PS3/Xbox 360. The game follows a salaryman named Vincent who's seduced by the titular Catherine, and soon afterward begins to have recurring nightmares about anthropomorphised sheep and climbing giant staircases.

Here you'll see some of those sheep and the twisted nightmare gameplay portions, which have Vincent navigating a tower made up of blocks full of obstacles and traps, whilst giant hands with a bloody fork stab around him. You can also hear bits of the Catherine's awesome soundtrack composed by Atlus/Shin Megami Tensei veteran Shōji Meguro.

Atlus will ship Catherine in Japan on February 17th -- details for a possible North American and European release are still forthcoming.
